I picked up a set of stax lambdas and and srm1-mk2 inexpensively. Since my last thread, I have had the amp restored (re-soldered and modified for pro bias). My sr-30 sound clean. My lambdas still have significant buzzing in the left channel at both frequency extremes. There is also a constant squeal/buzz only in the left ear. From what I read these symptoms can be the result of dust in the driver. After searching and reading through hundreds of pages in the stax thread, I cannot find a good answer.
What I've gathered so far:
1. Don't use a vacuum or compressed air.
2. People claim to have opened them up and removed particles (primarily hairs) but never state what method was used.
I have let them charge for a couple days with no noticeable improvement. The buzzes and squeals are annoying enough for me not to use them so at this point, I'm considering selling them as parts. If the left driver is shot anyways, I may as well try to fix it.
